Upgraded to WP 3.4.2 and nextgen slider widget stoed working

I’ve had the nextgen slider widget running fin for long time.

I just updated to WP 3.4.2 today and it stopped working.

It no displays an error that says:

Get the Flash Player to see the slideshow.

Anyone else have this problem? Any advice on how to solve it?

Thanks!
